If you are new to home audio, walking into the world of loudspeakers can feel like landing in a country where everyone speaks a different language. Words like "acoustic suspension," "sensitivity," and "crossover" get thrown around as if everyone already knows them. This guide fixes that. We are going to walk through the KLH Model Five floorstanding speaker in plain English, explain what every part does, and help you understand whether it is a good fit for you. No jargon left unexplained, and no assumptions about what you already know.
What Is the KLH Model Five, and Where Does It Fit?
What kind of speaker is the KLH Model Five?
The KLH Model Five is a large floorstanding speaker, meaning it stands on the floor on its own rather than sitting on a shelf or stand. It is tall enough (about 34 inches with its included base) to bring the sound up toward your ears when you are seated. Floorstanders like this one typically produce fuller, deeper sound than smaller speakers because they have more internal space and larger drivers (the cone-shaped parts that make the sound).
Where does the Model Five fit in a home audio system?
The Model Five is the pair of speakers you connect to an amplifier or receiver, which is the box that powers them and sends them the music. In a typical setup, your music source (a record player, streamer, or CD player) feeds into the amplifier, and the amplifier drives the speakers. You would place two Model Fives across the room from your listening spot, one on the left and one on the right, to create a full stereo image. They work beautifully for music listening and can also serve as the front speakers in a home theater system.
Where does the Model Five sit in KLH's own lineup?
The Model Five sits comfortably in the middle-to-upper part of KLH's range of floorstanding speakers. KLH also offers the smaller Model Three, the Model Four, and the larger Model Seven. The Model Five is a substantial, serious speaker that many listeners find hits a wonderful balance of size, sound, and room-friendliness.
The Drivers: What Makes the Sound
What does the 10 inch woofer do?
The 10 inch woofer is the large driver that produces the low frequencies, the bass you feel in your chest and the deep foundation under music. It is made of pulp-paper, which is treated paper pulp, a light and naturally well-behaved material that KLH tunes for a natural tone. A 10 inch woofer is generously sized, which is a big reason the Model Five can move enough air to deliver satisfying, room-filling bass.
What does the 4 inch midrange driver do?
The 4 inch midrange driver handles the middle frequencies, which is where most of the important detail in music lives, including voices, guitars, and pianos. It is also made of pulp-paper for the same natural, uncolored sound. By giving the midrange its own dedicated driver, the Model Five lets voices and instruments come through clearly without competing with the bass or the highs.
What does the 1 inch aluminum dome tweeter do?
The 1 inch aluminum dome tweeter reproduces the high frequencies, the airy detail like cymbals, the shimmer of strings, and the crispness of consonants in a singer's voice. It is a small dome made of anodized aluminum, a light and rigid metal that lets the tweeter respond quickly and cleanly for extended, detailed treble. This is the driver that gives music its sparkle and sense of openness.
Why does the Model Five use three drivers instead of one?
Using three drivers lets each one specialize in the part of the music it does best. This is what "3-way" means: the sound is split into three ranges (low, middle, and high), and each range is sent to the driver designed for it. The result is cleaner, more detailed sound than a single driver trying to do everything at once.
The KLH Design: Why It Sounds the Way It Does
What is acoustic suspension, and why does KLH use it?
Acoustic suspension means the speaker cabinet is completely sealed, with no holes or vents. The trapped air inside acts like a spring that controls the woofer's motion. This produces very tight, accurate, low-distortion bass that stays clean even when you turn things up loud, and it delivers deep bass from a more compact cabinet than a vented design would. KLH helped popularize this design in the late 1950s, and it defines the brand's signature sound. There is one gentle trade-off: sealed designs tend to draw a little more power from the amplifier, which is why the Model Five rewards a capable amp.
What does the reverse-roll rubber suspension do?
The reverse-roll rubber suspension is the flexible rubber ring (the surround) around the edge of the woofer cone, oriented in a specific way to control the cone's movement very precisely. This lowers distortion, meaning the bass stays clean and true rather than getting muddy or loose. It is one of those small engineering details that adds up to a better listening experience.
What does the Acoustic Balance Control do?
The Acoustic Balance Control is a small 3-position switch on the speaker that lets you raise or lower the level of the high frequencies in small steps. In plain terms, it lets you make the sound a little brighter or a little more relaxed to suit your room and your taste. Rooms with lots of hard surfaces can sound bright, while rooms with soft furnishings can sound duller, and this control lets you fine-tune the balance without any extra equipment. It is a KLH signature carried over from the original Model Five.
What is the slant-riser base for?
The slant-riser base is the angled plinth included with the speaker that tilts it back slightly. This gentle tilt aims the drivers so their sound reaches your ears in better alignment when you are seated, and it adds stability to the tall cabinet. The riser is why the speaker measures 34.25 inches tall with the base and 26 inches without it.
The Specifications: What They Mean in Real Life
What does a frequency response of 42 Hz to 20 kHz mean?
Frequency response of 42 Hz to 20 kHz means the speaker reproduces sound from deep bass (42 Hz) up to the highest highs most people can hear (20 kHz). The lower the first number, the deeper the bass, and 42 Hz is genuinely deep, enough to give music a solid, full-bodied foundation. The "+/-3 dB" part simply means the speaker stays accurate and even across that range.
What does a sensitivity of 90.5 dB mean in practice?
Sensitivity of 90.5 dB tells you how loud the speaker plays for a given amount of amplifier power, measured in-room. A higher number means the speaker plays louder with less power. At 90.5 dB, the Model Five is quite efficient and easy to drive to satisfying volumes, which is welcome news given that sealed designs can sometimes ask a bit more of an amp.
What does 6 ohms nominal impedance mean?
Nominal impedance of 6 ohms describes the electrical load the speaker presents to your amplifier. Most amplifiers and receivers handle a 6 ohm load comfortably. The specification also notes a 3.5 ohm minimum, which simply means the load can dip a bit lower at certain frequencies, so a solid, well-made amplifier is the ideal partner.
What does the recommended amplifier power of 20 to 200 watts mean?
The recommended range of 20 to 200 watts tells you the Model Five works well with amplifiers anywhere in that power range. You do not need a huge amplifier to enjoy them, but they will happily scale up with more power for bigger rooms or higher volumes. This wide range makes the Model Five easy to match with many systems.
What do the crossover frequencies of 380 Hz and 2,850 Hz mean?
The crossover frequencies are the points where the internal filter network hands the music from one driver to the next. Below 380 Hz the woofer takes over, between 380 Hz and 2,850 Hz the midrange handles things, and above 2,850 Hz the tweeter carries the highs. This careful division is what lets each driver focus on what it does best.
Build, Finishes, and Ownership
What are the cabinet finishes and how big are the speakers?
The Model Five comes in three real-wood finishes: English Walnut, Nordic Noir, and West African Mahogany. Each speaker measures 34.25 by 13.75 by 13 inches with the riser base and weighs 44 pounds on its own (52 pounds with the base). That weight is a good sign, since heavier cabinets tend to resist unwanted vibration and produce cleaner sound.
Why does KLH's heritage and build quality matter?
KLH's heritage matters because the brand, founded in 1957 by Henry Kloss, is one of the storied American loudspeaker names, and the modern Model Five revives that acoustic-suspension engineering with contemporary drivers and cabinets. This combination of proven sealed-box design and quality construction is why the speaker sounds and measures the way it does, and why it is built to last. It is backed by a 10 year warranty for real peace of mind.
Who Is the KLH Model Five For?
The Model Five is for someone who wants big, honest, room-filling sound with tight and accurate bass, and who appreciates real-wood craftsmanship and a design with genuine heritage. It suits music lovers building a stereo system as well as anyone wanting excellent front speakers for a home theater. If you value clean, natural sound that stays composed at any volume, and you want a speaker you can tune to your room with the Acoustic Balance Control, the KLH Model Five is well worth a listen.
